Benefits of technology

The present invention relates to a connector terminal design that allows for a smaller buffer portion to absorb any positional gap between two objects, even if the positional gap is slight. The buffer portion is curved in a width-wise and thickness-wise direction, making it easier to bend and absorb deflection compared to the first and second contacts. The connector terminal includes relatively thick first and second contacts, and a thin buffer portion that can bend more readily to absorb the deflection. The thinner buffer portion allows for more bending and flexibility compared to the contacts, while still maintaining rigidity. The connector terminal design also allows for a small pitch between the contacts, ensuring efficient arrangement.

Problems solved by technology

However, if the portion 73b is hammered to thereby have a smaller diameter, a metal density and hence a hardness of the portion 73b increases by being hammered, resulting in that the portion 73b is difficult to be bent.

first embodiment

[0077]The electric connector in accordance with the first embodiment of the present invention will be explained hereinbelow with reference to the drawings.

[0078]As illustrated in FIGS. 1 and 2, the electric connector 10 in accordance with the first embodiment may be used to electrically connect printed circuit boards equipped in an automobile to each other, for instance. The electric connector 10 electrically connects a printed circuit board P1 as an example of a first object to a printed circuit board P2 as an example of a second object.

[0079]The electric connector 10 includes a male housing 20 mounted on the printed circuit board P2, a female housing 30 mounted on the printed circuit board P1 and fit to the male housing 20, a plurality of connector terminals 40 arranged in a line in the male housing 20.

[0080]The male housing 20 is designed to be almost a rectangular parallelepiped. The male housing 20 is formed at opposite ends at a bottom with a pair of bosses 21 inserted into th...

second embodiment

[0100]The electric connector in accordance with the second embodiment of the present invention is explained hereinbelow with reference to the drawings. The female housing 30x in the electric connector 10x in accordance with the second embodiment is designed to include a plurality of female connector terminals into which the connector terminals 40 are inserted. In FIGS. 13 to 15, parts or elements that correspond to those of the electric connector illustrated in FIG. 1 have been provided with the same reference numerals, and will not be explained.

[0101]The electric connector 10x in accordance with the second embodiment, illustrated in FIGS. 13 and 14, includes a male housing 20x mounted on a printed circuit board (not illustrated) as a first object, a plurality of connector terminals 40 housed in the male housing 20x, a female housing 30x mounted on the printed circuit board P2 as a second object, and a plurality of female connector terminals 50 housed in the female housing 30x.

Abstract

A connector terminal includes a first contact at one end, a second contact at the other end, and a buffer portion, the connector terminal electrically connecting a first object connected to the first contact to a second object connected to the second object, the buffer portion being bent in accordance with a positional gap between the first and second objects, the buffer portion having a cross-sectional area smaller than the same of the first and second contacts.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a connector terminal for electrically connecting objects such as printed circuit boards to each other, and further to an electric connector including the connector terminal.[0003]2. Description of the Related Art[0004]There is known an electric connector including a plurality of needle-shaped connector terminals each having contact at opposite ends thereof, a male housing in which the connector terminals are arranged in a line and which is mounted on a first printed circuit board, and a female housing into which the male housing is fit and which is mounted on a second printed circuit board. The connector terminal at the contact formed at one end thereof passes a through-hole formed through the female housing, and is inserted into a through-hole formed through the second printed circuit board, thereby the first and second printed circuit boards are electrically connected to each other.[0005]In an...
